# Scaling of Entropy Production under Coarse Graining

@inproceedings{Cocconi2021ScalingOE, title={Scaling of Entropy Production under Coarse Graining}, author={Luca Cocconi and Guillaume Salbreux and Gunnar Pruessner}, year={2021} }

Entropy production plays a fundamental role in the study of non-equilibrium systems by offering a quantitative handle on the degree of time-reversal symmetry breaking. It depends crucially on the degree of freedom considered as well as on the scale of description. It was hitherto unknown how the entropy production at one resolution of the degrees of freedom is related to the entropy production at another resolution. This relationship is of particular relevance to coarse grained and continuum…

Non-Markovianity and negative entropy production rates.

- Mathematics, PhysicsPhysical review. E
- 2019

This work shows under which conditions a negative entropy production rate implies non-Markovianity and when it does not, and provides a consistent theoretical framework to study the finite-time thermodynamics of a large class of dynamics with a precise link to its non- Markovianicity.

Stochastic thermodynamics under coarse graining.

A general formulation of stochastic thermodynamics is presented for open systems exchanging energy and particles with multiple reservoirs. By introducing a partition in terms of "mesostates" (e.g.,…

Quantifying dissipation using fluctuating currents

- 2019

The determination of entropy production from experimental data is a challenge but a recently introduced theoretical tool, the thermodynamic uncertainty relation, allows one to infer a lower bound on entropy production, and a critical assessment of the practical implementation is provided.

Transformation properties of entropy production.

In systems subjected to external periodic driving the adiabatic, asymptotic, and transient entropy productions are evaluated and the extent to which they can be separately non-negative is determined.

Fluctuation relations and coarse-graining

We consider the application of fluctuation relations to the dynamics of coarse-grained systems, as might arise in a hypothetical experiment in which a system is monitored with a low resolution…

Static Approach to Renormalization Group Analysis of Stochastic Models with Spatially Quenched Noise

A new “static” renormalization group approach to stochastic models of fluctuating surfaces with spatially quenched noise is proposed in which only time-independent quantities are involved. As…

Publisher Summary This chapter discusses the systems coupled to two reservoirs of energy in such a way that there is a steady energy flow through the system. An example is a resistor in steady state,…

Network theory of microscopic and macroscopic behavior of master equation systems

A general microscopic and macroscopic theory is developed for systems which are governed by a (linear) master equation. The theory is based on a network representation of the master equation, and the…

We present a review of the recently developed landscape and flux theory for non-equilibrium dynamical systems. We point out that the global natures of the associated dynamics for non-equilibrium…
